Background: Flupirtine (FP) is found to antagonize both glutamate and N methyl, D aspartate (NMDA) and the current study was undertaken to elucidate a possible neuroprotective role of flupirtine against NMDA induced neurotoxicity in experimental rat model. Methods: Excitotoxicty was produced in rat and it is counteracted by flupirtine. The animals were grouped as Group 1 (vehicle treated), Group 2 (received NMDA+vehicle), Group 3 (received FP+NMDA only), and Group 4 (received FP+vehicle) and were observed of animal behavior and oxidative stress biomarkers and also mRNA expression using reverse transcriptase-polymerase chain reaction (PCR PCR) was performed to determine the level of mRNA expression of acetyl cholinesterase (AChE) and muscarinic cholinergic receptor (MChR) in brain samples (hippocampus) of experimental animals. Results: Depression effect induced by NMDA was reversed by flupirtine. Decrease in oxidative stress bio-markers associated with increase in the antioxidant enzyme activities in group 3 and 4 compared to group 1 and 2. Gene expression were up-regulated in group 2 compared to 1, 3 and 4. Flupritine treatment reversed these alterations. Conclusions: This study represents the neuroprotective characteristics of flupiritne against the excitotoxicity induced by NMDA in an in vivo rat models.
